I like the colors, but I think straightening the horizon and cutting off some of the black on the bottom would help
Depends on your software. In Lightroom you can rotate the image to level the horizon and crop in the 6x9 format to reduce the bottom. Another option would be to change the aspect to 1x2 which you could use to eliminate the dead space on the bottom.
How can you change the horizon?? I can crop the bottom off??
I have lightroom 4 where do I find these at??
